It should be OK after you fix the 1X10K resister solder issue.

Place a blank EPROM, do blank check, see if it do the blank check correctly.

What version adapter you are using? Any pictures available for your setup? So that I can take a close look on your setup.

It seems the adapter issue since you tested on a parallel willem programmer.

i waited months to get the parrelel willem fixed or tested with the 27c160s only to be told that the willem i bought here will not support it and buy the gq-3x from here. now i find what i was given in return has problems also. this is starting to tee me off.

Hi werejag,

You do not need a new adapter. You only testedthe middle one right?

The first one and last one should work too.

The first one you need to solder a ZIF socket or a DIP socket.

no zif socket fits in that due to the pins being too close to the other.

and the other non zif board didnt like the chips

If that one works for 27C160, then it should work on 27C4002.
If ZIF does not fit, then just solder a DIP socket on that location will be fine.

ok took off the zif sanded its edge so i can place a 40pin zif next to it. both fit perfectly with just enough space to move the levers.

but i still get the same error.

so what is the problem?

It is hard to believe this adapter works for 27C160 but not 27C4002. They are sharing same circuit.
Here is the schematic of this adapter, please check if anything wrong on the soldering/connection.
http://www.mcumall.com/support/16BitSchematic.pdf

If no error found, then check 27C4002 if they are all good to program.
